People with chronic adverse health conditions often monitor their vital signs at home using conventional medical equipment and/or wearable devices. Self-monitoring at home presents a number of potential issues including incorrect usage, non-compliance, and stigmatization. In response, researchers have started investigating how ambient sensors (i.e., sensors embedded into everyday objects) might be used as a low-effort means of improving the frequency and quality of vitals monitoring. This workshop discusses zero-effort ambient monitoring technologies, with a focus on people with cardiovascular disease. Participants will be introduced to relevant topics prior to engaging in group work and discussions to explore the new and trending area of autonomous physiological monitoring at home.
